OpenAI's new Agents API provides a managed runtime for AI agents, demonstrating near 3x performance improvement and 83% token reduction on ARC-AGI-3 by offloading context management, tool routing, and multi-agent orchestration from the model to a dedicated runtime layer.
This article details the end-to-end tool supply chain for AI agents, covering runtime tool injection, MCP/OpenAPI gateway authentication, pre-chat authorization gating, credential isolation, and architectural comparisons between prompt-only tools, hardcoded plugins, and unified gateway patterns.
A deep technical analysis of DeepSeek Harness (dsh), an open-source agent runtime that acts as a model exoskeleton — plugin-based architecture, 1,546-line core loop, session-log-driven design, and built-in data loop via HTTP extensions.
The article analyzes former CrowdStrike CTO Elia Zaitsev’s decision to leave and launch a $170 million AI‑focused cybersecurity fund, outlining AI‑native threats, gaps in traditional security architectures, six emerging security sectors, and the investment logic behind backing them.
